My chicks were living in an elevated coop with half inch square hardware cloth underneath and after day 3 of them being home I woke up to find 8 of the 12 dead. They were all pulled against the bottom and one was even in pieces. It was so horrible to see and I was so sad. And the survivors are all either missing a toe or toes and part of toes. And one even has damage to the side of its face. You think something came from under and tried pulling them through??? What do you think it was? We live in the country and my old flock was slowly killed off by foxes, coons, Hawks, coyotes. We are definitely trying hard to make our coop impenetrable.
